Elisha Chesley

I descend from Cynthia Chesley (b. 1804) who was the daughter of Elisha and Susan Chesley.Elisha may have been a son of the Joseph Chesley who died in Industry, ME in 1826, although I have yet to verify this connection.Does anyone know where I can find any information on Elisha Chesley and Joseph Chesley?Are these guys related in any way to the Philip Chesley that I keep reading about on this web site?
